Disc brake equipped Volagi in size 57cm under 16 lbs? I'll believe when I see it.I echo you must be new here. This has been debated several times and also in various magazines.
I just purchased a Volagi with disc brakes. I just liked the idea of discs and the ability to go with full carbon wheels down the road if I want with no issues. I also like supporting smaller companies.
Like everything else I think it depends on what type of riding you are doing. I chose my bike not just because of the discs but because I need a relaxed frame that performs well on climbs and longer distances.
As far as weight and wind resistance I would say these are negligible for my case. If I were doing racing or crits I would choose something different but I imagine most riders in this board could not feel the differences no matter what they claim. My bike should be sub 16 pounds and hopefully closer to 15.5 in a size. 57. That's a couple of pounds lighter than my current steel and carbon joy made by Taylor.
Specialized is coming out with a disc equipped Roubaix. Of course it's because of Volagi but I wonder how many people will think discs are a "great idea" then.
This is why I'm considering discs for my next road bike. I do much climbing in the mountains with capricious weather (blue skies to thunderheads in an hour or two) and precipitous descents. The weight difference doesn't bother me- I'm not racing.Living on the "wet coast", I use disc brakes on my all-weather-go-everywhere bike because they are so much better in the wet, there is no contest. In fact, I feel no perceptible change in performance between dry and wet conditions while using disc brakes. Water does not seem to bother disc brakes at all.
My race oriented bikes have regular rim brakes of course.
There's some truth to that—and it partly answers the OP's question of why disc brakes aren't used on road bikes. Marketing high-end road bikes has to take into consideration that many riders of such bikes want to look like actual racers (no underseat bag, no visible pump, no disc brakes, etc.). So while there are no functional reasons prohibiting disc brakes, there are marketing ones. Of course, if the UCI allows disc brakes and actual racers adopt them, disc brakes would cease to be dorky almost overnight.Disc Brakes are the new Dork Disks.
Disagree with you here. I will say that matching rotors and size is more important with disks.Aside from the increased weight and air resistance they add, I think another thing is reduced safety on long descents. I believe I've read they cool slower than rim tracks, making them more dangerous on long descents. Of course mountain biking and cyclocross will see this problem less often.
This is just one of the disc/phobias 'for the day' I was referring to. On many group pave rides, I hop on my K2 Enemy w 25c & some old Hayes Mags, (a decent aging model!). There are some VERY LONG descents, then extreme long steeps. Not only do I end up at the bottom first - by circumstance; every rim rider is "gripped", I can even pulse w greater pressure for the power needed, feel very safe, and my rotors get no more hot than other times, never any warpage. Just not enough heat. 160mm (I can rush the corners as fast as I want, if I want, great control.)Disagree with you here. I will say that matching rotors and size is more important with disks.
I've done this one long decent around here on a CX bike with disks (25 mm road tires though) and on my CAAD10 with rim brakes. Now, I only did this a few times, but I was faster on the CX bike. I also felt way more confident with the disks than the rim brakes.
With Kettle cycles now shipping these lite/heat dissipating carbon/ceramic rotors, the weight and heat issues will be less.
I wonder how many riders would pass on a bike because they did not want to be "different" on the group ride?
